Does PC3500 DDR Ram exist with 2-2-2-6 T1 Latency's

[thatsright]

I ask, as for my new P4c system I'm buying Kingston Hyper X PC3500 DDR 512 X 2 with timings of 2-3-3-7-T1.

I plan on overclocking my P4c 2.4 CPU on my ABIT IC7 MB with the Hyper X and I'm new to the Overclocking field with DDR anyway, so would having lower latency timings help me, or hurt me in my O'Cing endeavor? And is having the 2-3-3-7-T1 timings, is what is known as 'Loose' timings? That is what I am also kinda confused on.


So if anyone could give me a few pointers her, I'd greatly appreciate it, thanks a million.

Basically, the only latency most people believe matters is your CAS latency. CAS 2 is fast, 2.5 is average, 3 is slow. The CAS latency is the first number in the set of numbers given in a 2-2-2-6-T1 formula.

Latencies don't make a big difference in speed, and basically only add to synthetic benchmarks, in my experience. Thugsrook had a post a while ago about the subject, but I can't find it right now. To sum it up, most of the time, the faster the better, but it's really no big whoop and sometimes lower latencies can slow you down.

I'd basically recommend running the RAM at its recommended latencies, and only look at CAS 2 stuff. 2-3-3-7-T1 is pretty decent and pretty common for PC3200+ RAM it seems.

Basically, unless you sit and stare at Sandra benchmarks all day trying to juice out 100 more points, it's all in the mhz 🙂

OCZ PC-3500 dual channel EL Platinum has those timings, I believe. www.OCZtechnology.com

OOps, sorry, but close...

n-Force 2 Chipset timings CL 2 2-3-5; Intel Chipset CL 2-2-3-6

I disagree with MistaTastyCakes about memory timiimgs having no real world speed increase. In Many video games, the in-game FPS is much higher with faster memory timings. I'm not talking about benchmarks, just the FPS numbers that I see in the corner of my screen while playing. I run 2252 1t timings, because after hours of play on my favorite games, they all ran faster, at 1t than at 2t. Many games such as UT2003, and IL-2, are punishing to memory and CPU, and the faster memory timings can allow extra FPS without raising the FSB. In other applications, I agree with MistaTasyCakes, in that faster memory/timings gets you little, and you pay lot memory.

As far as what works, I've tried Corsair XMS and Kingston HyperX. Corsair XMS memory modules, all run faster than their posted specs, but don't believe it when they say 2.55 volts. My PC3200 runs solid at 190mhz FSB. Kingston HyperX modules are inexpensive, and also run at any timings. The Kingston HyperX PC2700 runs solid in my other computer, to 175mhz FSB at 2252 1t @ 2.65v. I haven't gone higher yet, as the chipset is KT266a. In short, if you are default FSB, all name brand overclocker memory should run 2252 1t without a hitch. You may need to adjust the voltages slightly with either of these brands.

As fas as your overclocking being hurt by the memory timings, I say no. If you get to a point that the board can't take the 1t command, then drop (on the second screen of your bios, I believe) the CPU Fast Command Decode to Fast, and that normally allows another 8-10 FSB. If you only overclock by multiplier/CPU, then the aggressive memory timings affect nothing.
